Spinner handle for valve wheels



March 24, 1964 T. s. HALLETT SPINNER HANDLE FOR VALVE WHEELS AND THELIKE Filed NOV. 15. 1961 United States Patent 3,125,899 SPINNER HANDLEFOR VALVE WHEELS AND THE LIKE Thomas S. Hallett, Sub. P.(). 28, Calgary,Alberta, Canada Filed Nov. 13, 1961, Ser. No. 151,946 1 Claim. (Cl.74-557) My invention relates to new and useful improvements in spinninghandles for valve wheels and the like.

It is well known, particularly in the oil industry, that various valvewheels have to be rotated in order to open and close certain valves. Thevalve wheels have to be rotated many times in order to obtain thenecessary movement of the valves controlled thereby and this is anonerous task particularly when several valves have to be operated.

By providing a spinning handle for the valve wheels, I have overcomethis disadvantage.

Although spinning handles have been in use, never theless the maindifficulty with such spinning handles is the securement thereof to thevalve wheel rims, inasmuch as said valve wheel rims are normally made ofa relatively hard steel. It is therefore difiicult to obtain a firmattachment unless the valve wheel rims are drilled and a pin is passedthrough the spinning handle body and the rim.

However this is an undesirable practice inasmuch as it weakens the rimsand also due to the hardness of the steel, it becomes an extremelydifiicult operation,

By providing a spinning handle which is clampable around the rim andwhich is provided with case hardened serrations adapted to bite into thesurface of the rim, I have overcome the principal disadvantages ofconventional spinning handles.

The principal object and essence of my invention is therefore to providea device of the character herewithin described which can readily bepositioned upon the rim of a valve wheel and can be tightened thereon toeliminate slippage.

A further object of my invention is to provide a device of the characterherewithin described which not only includes serrations on the top andbottom plates but also serrations on the lower end of the handle holdingbolt which can therefore be tightened down so that it bites into thesurface of the rim and makes a firm anchorage for the spinning handle.

Another object of my invention is to provide a device of the characterherewithin described which is simple in construction, economical inmanufacture, and otherwise well suited to the purpose for which it isdesigned.

With the foregoing objects in view, and such other objects andadvantages as will become apparent to those skilled in the art to whichthis invention relates as this specification proceeds, my inventionconsists essentially in the arrangement and construction of parts all ashereinafter more particularly described, reference being had to theaccompanying drawings in which:

FIGURE 1 is a sectional elevation of my device, sectioned in part toshow the interior thereof.

FIGURE 2 is an underside plan view along the line 2-2 of FIGURE 1.

FIGURE 3 is a top plan view along the line 3-3 of FIGURE 1.

FIGURE 4 is a fragmentary cross sectional elevation on an enlarged scalesubstantially along the line 44 of FIGURE 2.

In the drawings like characters of reference indicate correspondingparts in the different figures.

Proceeding therefore to describe my invention in detail, referenceshould be made to the accompanying drawings in which reference characterindicates, in phantom, the rim of a valve wheel.

My invention includes a clamp collectively designated ICC 11 consistingof a bottom plate 12 and a top plate 13. Both of these plates arehexagonal when viewed in plan and the inner surfaces 14 thereof areprovided with a plurality of concentrically located serrations 15 edgesharpened and case hardened in order to facilitate the engagementthereof with the aforementioned rim 10.

Bolts 16 pass through the top and bottom plates, nuts 17 clamping theplates to the rim 10.

The top plate 13 is apertured centrally as at 18 and is provided with anupstanding shoulder portion 19 surrounding the aperture 18. The aperture18 and the shoulder 19 are internally screw threaded and adapted toreceive a bolt 20 which extends through the shoulder 19 and the aperture13 so that the lower end 21 of the bolt can engage the surface of therim 111.

This lower end 21 is also provided with concentrically locatedserrations 22, edge sharpened and case hardened, which facilitate thegripping of the rim by the device.

In this connection a nut portion 23 is formed upon the bolt intermediatethe ends thereof and this nut portion facilitates the tightening of thebolt upon the rim It) in order to force the serrations 22 to bite intothe surface thereof.

An upward extension 24 of the bolt 20 is provided above the nut 23 andthis extension is provided with an annular groove 25 adjacent the outerend 26 thereof.

A spinning handle 27 is provided with a shoulder 28 which is aperturedand adapted to fit over the extension 24 of the bolt, screw threaded pin29 extending through an aperture in the shoulder 28 so that the innerend 30 of the pin seats within the annular groove 25. This preventsdisengagement of the spinning handle 27, yet at the same time allowsfree rotation thereof upon the aforementioned bolt extension 24.

Since various modifications can be made in my invention as hereinabovedescribed, and many apparently widely different embodiments of same madewithin the spirit and scope of the claim without departing from suchspirit and scope, it is intended that all matter contained in theaccompanying specification shall be interpreted as illustrative only andnot in a limiting sense.

What I claim as my invention is:

A spinning attachment for hand-manipulated wheels, said attachmentcomprising in combination a pair of spaced apart clamping plates adaptedto receive awheel rim therebetween, a pair of clamping bolts extendingthrough said plates, said plates having opposing surfaces each providedwith a plurality of concentric serrations for securely gripping thestated wheel rim when said bolts are tightened, a post provided on andprojecting outwardly from one of said plates in coaxial relation to saidconcentric serrations, and a handle rotatably mounted on said post, saidone of said plates being provided with a screwthreaded apertureconcentric with said serrations, said post having a screw-threaded innerend portion disposed in said aperture, and the inner end surface of thepost being formed with a set of concentric serrations for securelygripping the stated wheel rim when said post is tightened in saidaperture.
